Driving assist systems
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turn-
ing on slippery road surfaces
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
2704-5. Using the driving support systems
CT200h_OM_OM76102E_(EE)
The slip indicator light will flash
while the VSC/TRC/ABS systems
are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRC system may reduce
power from the hybrid system to the wheels. Pressing to turn the
system off may make it easier for you to rock the vehicle in order to free
it.
To turn the TRC system off, quickly
press and release .
The “TRC OFF” indicator light will
come on.
Press again to turn the system
back on.

TRC cannot be operated. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid system is
started, just after the vehicle begins to move, if the brake pedal is depressed
forcefully or repeatedly, or 1-2 minutes after the hybrid system is stopped. This
sound does not indicate that a malfunction has occurred in any of these systems.
Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering input over an extended period of time.
The steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the hybrid system off. The
EPS system should return to normal within 10 minutes.
Automatic reactivation of TRC system
After turning the TRC system off, the system will be automatically re-enabled in
the following situations:
When the power switch is turned off
The TRC will turn on when vehicle speed increases
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge from
the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden braking
operation.

The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick road.
Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC system is turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the system to help ensure vehicle stability and driving force, do not
turn the TRC system off unless necessary.
Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern and total load capacity. In addition, make sure that the tires are inflated
to the recommended tire inflation pressure level.
The ABS, VSC and TRC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for further information when replacing tires or wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Driving
CT200h_OM_OM76102E_(EE)
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Park the vehicle and shift the shift position to P and block the wheel
under the vehicle without setting the parking brake. The parking brake
may freeze up, preventing it from being released.
Use the correct tire chain size when mounting the tire chains. Chain size
is regulated for each tire size.
Side chain:
3 mm (0.12 in.) in diameter
Cross chain:
4 mm (0.16 in.) in diameter
Regulations regarding the use of tire chains vary depending on location
and type of road. Always check local regulations before installing chains.
Tire chain installation
Observe the following precautions when installing and removing chains:
Install and remove tire chains in a safe location.
Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
Install tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 - 1.0 km (1/4 - 1/2 mile).
Install tire chains following the instructions provided with the tire chains.

Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or seri-
ous injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit specified
for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and
may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting oper-
ations that cause sudden engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle control
is maintained.
When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move unex-
pectedly, possibly resulting in an accident.
NOTICE
Repairing or replacing snow tires (vehicles with the tire pressure warning sys-
tem)
Request repairs or replacement of snow tires from any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional or legitimate
tire retailers.
This is because the removal and attachment of snow tires affects the operation
of the tire pressure warning valves and transmitters.
Fitting tire chains (vehicles with the tire pressure warning system)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
